To remove numbers from the call log that you don’t want anyone seeing, then open your Call Log.

This will normally be found on your Apps list or you can also go to your Dialler and find Logs or Call Logs.

Then press and hold on the contact you want to remove. When the Menu appears, press Delete.

If you see an insufficient storage available error, or find that you’re running low on your phone memory (not to be confused with your SD Card memory), then there are a number of ways to fix this.

This error can be very frustrating as it often means you cannot install new Apps, and some Apps may not even function properly because of this. We hope this guide is as comprehensive as possible, but if you find other methods, then please suggest them in the comments below.

The first step is to determine exactly what is eating up your phone’s storage memory. To do this pull down your notifications menu and select Settings and find Storage. It may take a while to calculate so be patient. From here you can see whether it is your Applications, Pictures, Audio or otherwise, that is causing the problem. Obviously, if it is photos or music, then the first step is to remove some of these (ensuring you do actually want them deleted of course!).

If it is your Apps taking up space, then you have a few options, as follows:

Uninstall Apps – Go to Settings – Applications – Application Manager and swipe to the ALL tab at the top. Then look at the top of the screen which shows how much free space you have. Often you will have very little Free memory, which is the cause of the error. From here, press your Menu button and select Sort by size. This will show you which Apps take up the most space and which will make the most impact by removing. Obviously don’t delete things like Gallery (which will remove your photos!), Internet (which is your browser), key Google Apps and so on. However if you have Apps you don’t use anymore, then uninstall them to free up space.

Clear App Cache (with an App) – For this method, you will need to download an App called Clear App Cache. However, this will only work if you can uninstalled enough Apps to free up enough space to install the App itself. Once installed however you can quickly clear the cache of all of your Apps, which should free up some space.

Create Cloud Storage Backup – You can also select to create back-up in Google drive. For that Go to Settings – Backup & Reset and turn Back up data ?ON? and add your back-up account (Preferably the same account from which you signed in on Play Store). ?Then open Google Account icon and from there you can select folders for which you want to create back-up, you can also set frequency of creating back-up e.g. daily, monthly or weekly etc. Now you can delete data from folders for which you have opted to create back, but before that please make sure that back up has been created. You can access these files by signing in to Google drive using you Gmail email and Password.

Clear App Cache (manually) – Apps such as Gallery, can sometimes generate a large cache (image thumbnails in this case) which can be cleared to free up memory. First, go to Settings – Applications – Application Manager. Then swipe from right to left until you’re on the ALL screen. Then press the Menu key and Sort by size. Then choose the largest App by pressing on it. Then select Clear Cache. Do this until you’ve cleared as much space as you can. ?

Dump your log files – This will only work on some devices, however it doesn’t cause any data loss. It simply cleans up your App log files. Go to your phone dialler App and press: *#9900# ? Then Select delete dumpstate/ logcat and hit OK.

Move Apps to SD Card (if you have one) – Settings – Applications – Application Manager. Flick from right to left until you get to SD Card. Then simply tick which Apps you’d like to move from Phone memory to SD Card memory.

Clear Browser Thumbnails – This one seems to be a bug in some versions of Android and/or some phones, but is a very quick and effective fix. Simply open your stock Android Browser, which is usually found by opening the Internet App. Then at the top right check if you have multiple tabs open. If you do, then swipe them off the screen one by one until you have none left. This can clear up hundreds of cached thumbnails which never clear unless this process is carried out. It has been known to clear several gigabytes of space for users that don’t close their tabs often. ?

Check folder/file sizes – The last method is great and involves installing an App called DiskUsage from the Play store. Once you install this it will show you which folders are the largest. You can then drill down to find out exactly what is consuming your precious space before deciding to remove the files or folders. You can also integrate the App with File Explorer Apps to easily manage your files. When it comes to removing files and folders it’s sometimes easier to do that by plugging your device into a PC and browsing the folders that way.

If you find yourself woken up by notifications, text messages or incoming calls, then there are some handy features called Blocking Mode.

1. Pull down the drop down menu and choose Shortcut – Do Not Disturb

2. An alternate way is go to Settings – Device – Sounds – Do not disturb.

From here you can set a From and To time in which to block these notifications.

You can also allow notifications through from certain contacts that you don’t mind bothering you.

When entering text into Apps such as your Messaging App, Facebook App and so on, you can tap on the words to start selecting text. Normally, you would then drag the left and right sliders to select the word, or words you want to highlight.

If you double tap on a word however, it will quickly select that word. Very handy for quickly copying and one words, name or place.

Android now comes with a sound Equaliser so you can adjust your bass and treble.

Simply open a music file using the Music Player App.

Then go to Settings – Scroll down for Equalizer.

Then simply drag the sliders up and down to adjust the bass and treble.

There is a great app called Moves by a company called Protogeo that makes use of your devices accelerometer to record your movements, whether by walking, cycling or running.

Go to the Play Store and search for Moves.

If you are browsing and have zoomed in or out and the column you’re reading doesn’t fit the screen properly, you can pinch to zoom in. Then double tap on the column. The column will then be reformatted to fit the screen width.

To see notifications on your Lock screen, the best option is to download an App called NoLed from the Play Store. This will show notifications such as text messages, emails and missed calls as bright icons on your homescreen.

You can choose between very small squares or small icons and these can assigned by coloured.

Follow this guide if you want to check the data and WiFi usage on your Lg K40.

In this day and age, staying connected is essential. However, whether we like it or not, most mobile data plans put a limit on our data usage each month.

Browsing through Social Media may be fine, but downloading and streaming content can easily eat up on your monthly data allocation.

Reaching your data cap means that you cannot stay online for the rest of the month. Worse, you may be allowed to go online but it also means a huge bill by month’s end.

  1. Go to Settings → Connections → Data Usage
  2. From there, you can set a limit or data cap for a certain time period or billing cycle (a week, month, etc).
  3. You may also press the Menu option and tap “Restrict Background Data Usage.” This option will help you manage your data usage, especially for apps that run in the background (such as Instagram and Messenger). However, this also means that the apps may stop working properly.

To check WiFi usage on the Lg K40, follow these steps:

  1. Go to Settings → Connections → Data Usage
  2. From there, tap on the Menu button (3 vertical dots on the upper-right corner of the screen).
  3. Tap on “Show WiFi” then “Wi-Fi data usage.”

Alternatively, some Android handsets may need to follow these steps below:

  1. Go to Settings → WiFi & Internet → Data Usage
  2. Tap WiFi Data Usage to view WiFi stats.
  3. From this menu, you can also view data/WiFi usage per app.

The methods above generally work for most Android phone devices. Some handsets may have slight variations, you should just look for something similar Connections, Networks, or Data Usage menus.

Huawei users however have to follow a different process. Below is a short guide to check data and WiFi usage for Huawei phone users:

  1. Go to Optimizer → Data Usage
  2. From there, you can view your data usage for the month.
  3. You also have a Smart Data Saver feature. You may turn that on if you want to.
  4. You can also tap on the apps which are shown to be big data consumers and adjust their usage/consumption accordingly.
  5. You may also set a limit by tapping “More Data Settings” then “Monthly Data Limit.”

Most Android devices come with an alternative way of entering text called Swype. Many prefer this method and believe it is quicker.

When any text entry box appears, press and hold the box. Then select Input method: SWYPE. Once enabled, you simply drag your finger around the keyboard moving over the letters in the correct order to spell a word.
